Abstract: A radiator for the motorcycle includes a core through which a cooling medium flows, a cooling fan which is disposed on a downstream side of the core and ventilates the core, a downwardly opened fan covering for enclosing areas above, on opposite lateral sides and on a downstream side of the cooling fan, and a partition wall for partitioning between an lower portion of the core and a lower portion of the cooling fan so as to suppress the backward flow of the discharge air from the opening towards the core.

Abstract: A sludge receiving facility is provided with upper and lower structures respectively having inner spaces communicating with each other, wherein sludge tanks each having a sludge charging port are provided in the lower structure, and a partition wall configured to partition a carrying-in space of the upper structure from the inner space is provided, the sludge receiving facility including: outside air blowing means; air circulating means configured to enable the inner space and the carrying-in space to communicate with each other; first exhausting means configured to exhaust air from an upper part of the carrying-in space; second exhausting means configured to exhaust air above the sludge charging port; and third exhausting means configured to exhaust air inside the sludge tanks, wherein opening/closing means are respectively provided in the circulating means and the first to third exhausting means.
